Phase 2 SBIR

Agency: National Aeronautics and Space Administration
Topic: 07-2
Budget: 01/01/07 - 12/31/07

Loop Heat Pipe (LHP) is a high performance heat transport device using capillary forces to circulate the working fluid in a closed loop. Conventional LHPs usually have one capillary pump (evaporator) to acquire waste heat from a heat source. Recent efforts have focused the development of LHPs that contain two or more evaporators. Even though ...

Phase 1 SBIR

Topic: 06-1
Budget: 01/01/06 - 12/31/06

Significant cost and weight savings of a space mission can be achieved by improving the cryogenic storage technology. Added cryogen mass due to the cryogen boil-off, the oversized tanks and storage systems make the planetary missions prohibitive. The recently proposed Zero-Boil-Off (ZBO) strategy for cryogen tanks, which combines both thermal ...

Budget: 01/01/06 - 12/31/06

Cooling electronic components in the space environment still remains a challenge for thermal engineers. In the currentdesign practice, copper straps are used to transfer the waste heat from various high-power dissipating components tothe side walls of the electronic box. Another heat transport device then collects the waste heat from the box mou...

Budget: 01/01/04 - 12/31/04

Laser diodes are the key component in many space-based applications ranging from communication systems to optical sensors/detectors. Laser diode emitters however dissipate large amounts of waste heat of their own from the small footprint of the device. As a result, the dissipating heat flux from the laser diodes can reach a level as high as 1kW/...

Next generation Far Infrared (FIR) Space Telescopes such as NASA?s SAFIR, SPIRIT, and SPECS require the entire mirrors, which can be as large as 10 meters in diameter, to be cooled to the temperature range of 4-40K. To meet the challenging cooling requirements of the missions mentioned above, TTH Research proposed the development of an advanced ...

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 03-1
Budget: 01/01/03 - 12/31/03

To take full advantage of the space environment, Far Infrared (FIR)/Submillimeter (SMM) interferometers require cold mirrors (4 K) and detectors (0.1 K or colder). The collecting mirrors for the proposed FIR/SMM missions are large. The most difficult challenge will be the 4K cryocooling of the entire telescope structure. Given long duration of t...

Phase 1 SBIR

Agency: Missile Defense Agency
Topic: BMDO02-007
Budget: 05/14/02 - 02/17/03

At present, a passive cryogenic cooling technology that is lightweight and flexible for on-gimbal cryogenic cooling applications is non-existent or, at best, incomplete. Cryogenic Capillary Pumped Loops (CCPLs) demonstrated that they were capable of providing several watts of cooling at 77K. However CCPLs required intrinsically rigid liquid co...

Phase 1 SBIR

Topic: 02-1
Budget: 01/01/02 - 12/31/02

The Next Generation Space Telescope (NGST) program has identified the need for cryogenic cooling transport devices that can provide cryogenic cooling in the temperature range of 20-30K, minimize vibration effects of cryocoolers on instruments, minimize spatial temperature gradient in cryogenic components, level out thermal loads from duty-cycled...

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 02-1
Budget: 01/01/02 - 12/31/02

The National Aeronautics and Space Administration (NASA) centers have incorporated or is contemplating the use of Loop Heat Pipes (LHP) in many of their current and future spacecraft designs. However, there is currently no means for a typical spacecraft thermal engineer, with limited technical knowledge of two-phase flow and LHP technology, to i...
